- ADCMT Optical Power Meter 8250A
Bench-type optical power meter suitable for R&D and production of optical disks
The 8250A is a bench-type optical power meter, which is most suitable for R&D and production of LDs, optical pickups, and drives for optical disks. It has 0.001 dB resolution and 5½-digit display and is also equipped with GPIB and USB interfaces as standard, allowing easy automated system establishment.
Nine kinds of optical sensors with various purpose (general-purpose, blue-violet, high-power, three-wavelength) and different shapes (thin-type, cylindrical-type) are available. The three-wavelength optical sensors 82314B, 82324B and 82314BW are capable of measuring 405 nm, 650 nm, 780 nm wavelength ranges.
The blue-violet optical sensors 82312B and 82322B have realized a flat wavelength sensitivity characteristic and low dependency on an angle of incidence in the 405 nm range. The high-power optical sensors 82313B and 82323B enable high-power measurement of up to 200 mW.
Furthermore, the optical sensors for the TQ8210/TQ8215 series are also usable.

Functional Descriptions
High-resolution measurement and large-sized display
By adopting low-noise design and a high-resolution A/D converter, the 8250A achieves measurement with a high resolution of 0.001 dB that never overlooks subtle change.
Nine types of optical sensors to meet various applications
● Blue-violet sensors to measure lasers of Blu-ray Disc
To measure blue-violet lasers precisely, the 82312B and 82322B blue-violet sensors have realized a maximally flat wavelength sensitivity characteristic. This saves time in performing sensitivity correction at each measurement and always offers high-accuracy measurement results.
82312B
82322B
● Three-wavelength sensors to measure lasers with different wavelengths
The 82314B, 82324B and 82314BW sensors are capable of measuring all lasers of 405nm wavelength for Blu-ray Disc, 650 nm wavelength for DVD and 780nm wavelength for CD. In the range from 400 to 420nm wavelengths in particular, sensitivity correction is unnecessary because of the flat wavelength sensitivity characteristic. In other wavelength ranges, the wavelength sensitivity values stored in the sensor help easy operation.

82324B
● High-power sensors to measure high-power lasers for write
The power output of a laser disc for write such as CD-RW exceeds 100mW at the peak even with a pickup installed. The 82313B and the 82323B are high-power sensors capable of measuring up to 200mW with high accuracy. These sensors have high linearity up to 200mW approximately even at beam spot of 0.1mm diameter.

82323B
● Low-priced and easy-to-use general-purpose sensors
The 82311B and the 82321B are low-price general-purpose sensors that can be used in a wide wavelength range from 390nm to 1100nm. The calibration wavelength is 780nm and the correction value is stored in the sensors. Sensitivity correction of other wavelengths is also available by using the options.
82311B
82321B
● Both thin types and cylindrical types
Two shapes of sensors can be selected for each purpose. Thin types of sensors are convenient for measuring optical power in a limited space with a pickup installed, and cylindrical types of sensors are used for measuring the output power from a fiber with an optical bench.
